��ҹѰ�� researchers have been selected for funding from The Advanced Research + Invention Agency (ARIA) to help improve our understanding of climate tipping points.

These tipping points are critical thresholds in the climate system that, if crossed, could lead to drastic and irreversible changes, such as widespread flooding, biodiversity loss, and threats to food security in the Arctic and North Atlantic.

The funding is part of , which aims to develop an early warning system for these climate shifts. This five-year initiative, backed by £81 million, brings together 27 international research teams to detect early warning signs of tipping points.

Climate tipping points have the potential to impact billions of people worldwide. If, for example, the Greenland Ice Sheet reaches a tipping point and collapses, it could significantly alter ocean currents and increase sea levels, leading to more frequent and severe flooding events. Currently, even our most advanced climate models struggle to predict exactly when such tipping points will occur or what their full consequences will be.

To address this challenge, the programme will focus on three key areas:

- Developing sensing systems to monitor the ocean and frozen regions (cryosphere).

- Deploying these systems in critical locations, including the Greenland Ice Sheet and North Atlantic.

- Improving computational models to better predict tipping points and their consequences.

Among the funded projects, a major initiative called GRAIL (GReenland ice sheet to Atlantic tipping points from Ice-sheet Loss), which involves ��ҹѰ�� researchers and is led by the British Antarctic Survey. It aims to understand how the melting of Greenland’s glaciers releases freshwater to the North Atlantic, affecting ocean circulation and the global climate.

Researchers will use advanced sensors and AI-driven models and robotics to track ice melting and iceberg production, providing never-before seen data for early warning systems.

GRAIL project scientist Dr Alison Cook of ��ҹѰ�� said: “Greenland is of particular interest to environmental science as it is losing ice mass faster than anywhere else on the planet. In order to anticipate how this will affect our climate, we need to have better forecasts of ice melt and a clearer understanding of the wider impacts.

“��ҹѰ�� has a multi-faceted contribution to the project through autonomous underwater vehicles and drones, as well as specialisms in oceanographic modelling and photogrammetry. We will use state-of-the-art technology, underpinned by the knowledge and experience gained from our long history of Arctic observations, to investigate these crucial ice-ocean interactions.”

Dr Kelly Hogan, a marine geophysicist at BAS and R+D Creator on the GRAIL project, explained the importance of this work:

“Greenland is the fastest melting place on Earth, but this ice loss has knock-on effects for both North Atlantic ocean currents and fisheries. This crucial research will help us to understand how much freshwater the ice sheet is releasing, and what the subsequent effects will be on the ocean currents that bring warm waters and weather to the UK.

“This is now urgent work for us to do so policymakers can understand what will happen in the North Atlantic and set out appropriate adaptation and mitigation plans. Some computer models predict that large changes in the Atlantic Ocean could happen as soon as the 2040s so this is a key moment for us to investigate this Greenland Ice Sheet tipping point.”

This funding is subject to final contract negotiation.
